Redis-rs is a high level redis library for Rust. It provides convenient access to all Redis functionality through a very flexible but low-level API. It uses a customizable type conversion trait so that any operation can return results in just the type you are expecting. This makes for a very pleasant development experience.
The crate is called redis and you can depend on it via cargo:
[dependencies]
redis = "0.5.3"Documentation on the library can be found at mitsuhiko.github.io/redis-rs.
To open a connection you need to create a client and then to fetch a connection from it. In the future there will be a connection pool for those, currently each connection is separate and not pooled.
Many commands are implemented through the Commands trait but manual
command creation is also possible.
extern crate redis;
use redis::Commands;
fn fetch_an_integer() -> redis::RedisResult<isize> {
// connect to redis
let client = try!(redis::Client::open("redis://127.0.0.1/"));
let con = try!(client.get_connection());
// throw away the result, just make sure it does not fail
let _ : () = try!(con.set("my_key", 42));
// read back the key and return it. Because the return value
// from the function is a result for integer this will automatically
// convert into one.
con.get("my_key")
}If you want to develop on the library there are a few commands provided by the makefile:
To build:
$ make
To test:
$ make test
To run benchmarks:
$ make bench
To build the docs:
